Sitting on the edge. After barrelling across the US in an RV, you should stop at the Grand Canyon and stay put for several days. If you're brave, but not THAT brave, you can take the bus about half way and then start walking/hiking toward Hermit's Rest. Get there in time to catch the sunset. Be sure to stop several times along the way to sit for a moment and marvel or eat the lunch you packed for the long walk (take ALL your trash with you, do not leave anything behind). The areas near the bus stops tend to be busy so take advantage of the remote location and avoid the crowds--pick places to stop that are in-between the bus stops!! :) After you watch the sun set at Hermit's Rest, take the bus back into town. It's REALLY amazing how dark it gets.
